I now have everything I need to give a thorough critique. Here is my detailed editorial review:
Rabies Epidemiology Fact Sheet - Editorial Feedback
Overall, the sheet has a solid structure and covers the right categories. There are several factual inaccuracies, missing data points, formatting issues, and one section that needs to be significantly reworked. Here's a section-by-section breakdown:
Disease Overview
Causative Agent - INCORRECT
Written as: Lyssavirus
This needs to be more specific. The causative agent of classic rabies is Rabies lyssavirus (formerly Rabies virus, RABV), which is genotype 1 of the genus Lyssavirus, family Rhabdoviridae. Just writing "Lyssavirus" is the genus, not the species - it's like saying a patient has a "Coronavirus" without specifying which one. Fix: Rabies lyssavirus (RABV), family Rhabdoviridae.
Short Description - INCOMPLETE
Written as: "Rabies is a viral zoonotic disease that causes progressive and fatal inflammation of the brain and spinal cord."
This is acceptable but vague. Consider adding that it is transmitted via infected animal saliva, and that it is vaccine-preventable. A stronger version:
"Rabies is a vaccine-preventable viral zoonotic disease caused by Rabies lyssavirus that causes progressive, fatal encephalomyelitis. Transmission occurs through the saliva of infected mammals, typically via bites."
Epidemiology Data
Incidence - LIKELY INCORRECT / CONFUSING
Written as: 14,075.51 per 100,000
This number is almost certainly wrong or mislabeled. An incidence of 14,075 per 100,000 would mean ~14% of the population is affected - that would make rabies one of the most common diseases on Earth. WHO estimates approximately 59,000 human deaths annually, predominantly in Asia and Africa. The global incidence rate is approximately 0.76 per 100,000 population. If this number came from a specific regional or animal-based dataset, it needs to be clearly labeled with its source population. As written, it is misleading at best and incorrect at best. This needs to be corrected and clearly cited.
Prevalence - INCORRECT / MISUSED TERM
Written as: 52% in humans
Prevalence of 52% in humans makes no sense for rabies - that would mean over half the human population has active rabies infection. Rabies is an acute fatal disease, so point prevalence is essentially zero in any given moment for the general population. Prevalence is not a meaningful metric for rabies. This field should either be:
- Left blank/N/A with a note explaining why
- Replaced with a more useful figure like: "~59,000 estimated deaths/year globally (WHO)" or "15 million+ people receive PEP annually"
The 52% figure likely refers to something else (perhaps the proportion of cases in a specific subgroup from one of the cited papers), but as written it is incorrect and will confuse the reader.
Mortality Rate
Written as: 2.09 per 100,000
This is plausible for a regional figure but needs a clear source and denominator (per 100,000 what? global population? African population?). The WHO figure of ~59,000 deaths/year globally works out to about 0.76 per 100,000 globally. A rate of 2.09 may be accurate for a specific high-burden region - specify which population this applies to and cite the source.
Case Fatality Rate (CFR) - CORRECT
Written as: 100%
This is correct - once clinical symptoms appear, rabies is virtually 100% fatal (WHO). Good.
Trend
The sheet marks "increasing" but provides no data or citation to support this. Global trend data is mixed - some regions are declining due to vaccination programs. Either cite a source for the increasing trend or reconsider this - the WHO's "Zero by 30" initiative suggests a declining trajectory is the goal and some regions are achieving it.
Descriptive Epidemiology
Who is most affected - PARTIALLY CORRECT
Written as: Children between 5-14 years of age
WHO states children between 5 and 14 are frequent victims, and that 40% of deaths are children under 15. The age range in the sheet is correct but could be expanded: "Children aged 5-14 are most frequently bitten; 40% of all rabies deaths occur in children under 15 (WHO)."
Where is it most common - CORRECT
Written as: African and Asian countries
Correct. Over 95% of human deaths occur in Asia and Africa.
When does it peak - NEEDS CITATION
Written as: peaks in childhood and working age
This is plausible but needs a citation. Also, "working age" is vague - consider specifying the age range (e.g., 15-59).
23% in animals - this statistic floating at the top of the descriptive box is unclear. 23% of what? Cases? Deaths? In which country? This needs context and a citation, or should be removed.
Risk Factors
Lifestyle, Environmental, Biological, Behavioral - these are all correct and appropriate categories.
- Biological: "species of animal involved, site of exposure" - Good, but consider adding "wound depth and severity" as bite location (head/neck vs. extremity) and depth significantly affect incubation and PEP urgency.
- Behavioral: "lack of awareness, delayed care" - Correct. You could add "not completing PEP course" and "lack of pre-exposure prophylaxis in high-risk groups" as important behavioral risk factors.
Transmission & Public Health Impact
How it spreads
Written as: "bite of rabid animal"
Technically correct but incomplete. Transmission can also occur via scratches and mucous membrane contact with infected saliva (e.g., eyes, mouth). WHO specifically notes bites, scratches, and direct mucosal contact. Fix: "bite, scratch, or mucosal contact with saliva of a rabid animal."
Long-term complications
Written as: "incubation can be as long as 6+ years sometimes"
Two issues here:
- This belongs under "incubation period" not "long-term complications." Incubation ≠ complication.
- The standard WHO-cited incubation is 1-3 months, with the range being 1 week to 1 year, and rarely longer than a year. The 6+ year figure comes from rare case reports and is exceptional, not representative. If kept, it must be clearly cited as an extreme outlier. A better entry for this field: "Neurological sequelae reported in the rare survivors; most cases are fatal once symptomatic." (This is backed by your own cited reference at the bottom.)
Effect on community - INCOMPLETE
Written as: "significant emotional stress of families"
True, but undersells the public health impact. Consider adding: economic burden (~US$8.6 billion/year globally), loss of productive years (mostly deaths in working-age adults and children), and healthcare system strain from PEP delivery.
Control & Management / Prevention
Treatments or vaccines
Written as: "Post-exposure prophylaxis"
Correct but incomplete. PEP consists of three components: (1) wound washing, (2) rabies vaccine series, and (3) rabies immunoglobulin (RIG) when indicated. Just saying "PEP" without components is vague for a fact sheet. Also, pre-exposure prophylaxis (PrEP) for high-risk groups (veterinarians, lab workers, travelers) should be mentioned.
Rabies Vaccines - listed under prevention, which is correct.
Public Health Programs
Written as: "wildlife rabies surveillance, track and test human and animal rabies cases"
Good, but missing the single most impactful intervention: mass dog vaccination. WHO's "Zero by 30" strategy is built around vaccinating 70% of the dog population. This is a major omission for an epidemiology fact sheet.
Recommendations for students
Written as: "if dog bite, get prophylaxis :D"
The emoji and casual tone are fine for a personal note but should be removed for a submitted academic assignment. Also, the recommendation should specify: "seek PEP immediately after any animal bite, scratch, or mucosal exposure - do not wait for symptoms."
Quick Facts
World Rabies Day - CORRECT
28 September and the Louis Pasteur reference are both accurate.
General Formatting Notes
- The "23% in animals" figure at the top of the descriptive column is orphaned - it has no context. Connect it to a sentence.
- The trend arrow should match your cited data - if your sources show a decreasing trend in some regions, consider qualifying it.
- All statistics need inline citations (not just a reference list at the bottom). An epidemiology fact sheet should have superscript numbers or parenthetical citations next to each data point.
- The reference list at the bottom is good - but verify that the PubMed link (40535976) and the journal links match the specific statistics used in the sheet.

give me exact stuff I should out in those fields
Here is exactly what to put in each field, ready to copy in:
Disease Overview
Name of disease:
Rabies
Causative agent:
Rabies lyssavirus (RABV), family Rhabdoviridae
Short description:
Rabies is a vaccine-preventable viral zoonotic disease caused by Rabies lyssavirus that produces progressive, fatal encephalomyelitis. Transmission occurs via saliva of infected mammals, typically through bites. Once clinical symptoms appear, it is virtually 100% fatal.
Epidemiology Data
Incidence:
~0.76 per 100,000 population globally; estimated 59,000 human deaths per year (WHO)
Prevalence:
Not applicable - rabies is an acute fatal disease with no chronic carrier state. Point prevalence in the general population is effectively zero.
Mortality rate:
~0.76 per 100,000 globally; highest in sub-Saharan Africa and South/Southeast Asia where rates reach 1.5-4 per 100,000
Case fatality rate (CFR):
~100% once clinical symptoms appear
Trend:
Stable to slowly decreasing globally due to expanding dog vaccination programs; still increasing in some low-income regions with limited PEP access
Descriptive Epidemiology
Who is affected most?
Children aged 5-14 are the most frequent bite victims; 40% of all rabies deaths occur in children under 15. Males are more commonly affected than females.
Where is it most common?
Africa and Asia account for >95% of global human deaths. India alone accounts for ~36% of global rabies deaths. Highest burden countries: India, China, DRC, Ethiopia, Bangladesh.
When does it peak?
No strong seasonal pattern. Peaks in childhood (ages 5-14) and productive working age (15-59). Incubation period is typically 1-3 months (range: 1 week to 1 year; rarely longer).
Risk Factors
Lifestyle:
Dog ownership, livestock farming, living in rural areas near wildlife, occupational exposure (veterinarians, wildlife workers, lab workers)
Environmental:
Geographic location in Africa or Asia, proximity to wildlife habitat, limited access to PEP and healthcare, low dog vaccination coverage in community
Biological:
Species of animal involved (dogs account for 99% of human cases), bite site (head/neck bites carry higher risk due to proximity to CNS), wound depth and severity, immune status of the exposed individual
Behavioral:
Lack of awareness of PEP, delayed or incomplete PEP after exposure, no pre-exposure prophylaxis in high-risk individuals, allowing unvaccinated animals near children
Transmission & Public Health Impact
How it spreads:
Bite, scratch, or direct mucosal contact (eyes, mouth, open wounds) with saliva of an infected animal. Dogs are responsible for 99% of human cases. Person-to-person transmission is extremely rare (documented only via organ transplant).
Long-term complications:
Virtually all symptomatic cases are fatal. Rare survivors (fewer than 20 documented worldwide) have had serious and permanent neurological sequelae including cognitive impairment, spasticity, and behavioral changes.
Effect on community:
~US$8.6 billion global economic burden per year (WHO). Loss of productive life years, psychological trauma in families, healthcare system strain from PEP delivery, and significant underreporting due to limited surveillance in endemic regions.
Control & Management / Prevention
Treatments or vaccines:
Post-exposure prophylaxis (PEP): (1) immediate thorough wound washing with soap and water, (2) WHO-approved rabies vaccine series (days 0, 3, 7, 14), and (3) rabies immunoglobulin (RIG) infiltrated at the wound site when indicated. PEP is nearly 100% effective if started promptly before symptoms appear. Pre-exposure prophylaxis (PrEP) is recommended for high-risk groups (veterinarians, travelers to endemic areas, lab workers).
Public health programs:
Mass dog vaccination (target: ≥70% dog population coverage - the cornerstone of WHO "Zero by 30" strategy), wildlife rabies surveillance, tracking and testing of human and animal cases, improved PEP access in low-income settings, One Health surveillance integrating human and animal health data.
Prevention measures:
Rabies vaccines (pre- and post-exposure), responsible pet ownership and dog vaccination, avoiding contact with wild or stray animals, immediate wound washing after any animal bite, seek PEP without delay after any potential exposure.
Recommendations for students:
After any animal bite, scratch, or saliva contact with mucosa - wash the wound immediately with soap and water for at least 15 minutes, then seek PEP as soon as possible. Do not wait for symptoms to appear. PEP is ineffective once clinical signs develop.
Quick Facts
Did you know?
28 September is World Rabies Day, established to raise global awareness about rabies prevention and honor Louis Pasteur, who developed the first rabies vaccine in 1885. Over 29 million people receive rabies PEP annually worldwide (WHO).
can you not mix up the 8 fields
Looking at the template again, the 8 fields that had problems were:
1. Incidence
0.76 per 100,000 population globally (~59,000 deaths/year)
2. Prevalence
N/A - rabies is acute and fatal; no chronic carrier state. Use: ~15 million people receive PEP annually (WHO)
3. Mortality rate
0.76 per 100,000 globally; up to 1.5-4 per 100,000 in high-burden regions (Africa, South Asia)
4. Causative agent
Rabies lyssavirus (RABV), family Rhabdoviridae
5. How it spreads
Bite, scratch, or mucosal contact (eyes, mouth, open wounds) with saliva of infected animal; dogs cause 99% of human cases
6. Long-term complications
Rare survivors have permanent neurological sequelae (cognitive impairment, spasticity). Virtually all symptomatic cases are fatal.
7. Treatments or vaccines
PEP: wound washing + rabies vaccine series (days 0, 3, 7, 14) + rabies immunoglobulin (RIG) when indicated. Pre-exposure prophylaxis (PrEP) for high-risk groups.
8. Public health programs
Mass dog vaccination (≥70% coverage), wildlife surveillance, tracking human/animal cases, improved PEP access in endemic regions (WHO "Zero by 30" strategy)
what would be easier and unique disease to make a data sheet about with valid reliable sources
Here are some good picks across different categories - all have solid WHO/CDC/PubMed data:
Easy to source, not overdone
Tetanus
- Clear causative agent, well-defined CFR, strong WHO/CDC data, dramatic neonatal tetanus stats, obvious risk factors and prevention story. Very few students pick it.
Leptospirosis
- Underrated zoonosis with great epidemiology data, clear geographic distribution, distinct risk factors (flood exposure, occupational), good WHO burden estimates.
Dengue
- Tons of data, clear incidence trends (it's actually increasing globally), great maps, well-defined at-risk populations, strong CDC/WHO sourcing. Very visual.
Unique picks that stand out
Hantavirus
- Interesting transmission (rodent droppings, not bites), Americas vs. Asia strains differ, dramatic CFR (~36%), clear environmental risk factors. Less commonly chosen.
Scrub Typhus
- Massive burden in the Asia-Pacific that most students have never heard of, estimated 1 billion at risk, ~1 million cases/year, good recent PubMed data.
Melioidosis
- Called a "hidden killer," WHO only added it to NTD list in 2021, estimated 165,000 cases/year with 89,000 deaths, concentrated in SE Asia/Australia. Very unique choice.
My recommendation
Dengue if you want easy sourcing and lots of data to work with.
Melioidosis or Scrub Typhus if you want to stand out - your professor will likely not see another one on that disease, and the data is solid and well-cited in recent literature.
hantavirus was very focus on. news recently
Searching the Web
hantavirus outbreak 2025 2026 news
Yeah, hantavirus is extremely relevant right now. Here's the situation:
Why Hantavirus is a perfect pick right now
The current outbreak (May 2026):
- A cluster of cases broke out aboard the cruise ship MV Hondius in the Atlantic, with 7 cases (2 confirmed, 5 suspected) and 3 deaths as of early May 2026
- WHO issued a formal disease outbreak notice on 2 May 2026
- The strain involved is the Andes virus - notably one of the only hantavirus strains known to spread human-to-human, which is why it got global attention
- The outbreak is linked to Argentina, where mortality has recently jumped to ~30%, up from the historical ~15%
- WHO's current risk assessment for the general public is still low, so it's not a pandemic scare - but it's very much in the news
Why this makes your fact sheet stand out
- Timeliness - your professor will immediately recognize the relevance to current events
- WHO has just published fresh data - so your sources are brand new and credible
- The Andes strain vs. Sin Nombre strain distinction is a great epidemiological talking point (one spreads human-to-human, the other doesn't)
- The cruise ship angle is a unique transmission context worth including in your public health impact section
- Gene Hackman's wife died of hantavirus earlier this year too - another recognizable reference
Go with hantavirus. You'll have no trouble finding sources and it will be the most current, relevant sheet in your class.

HANTAVIRUS - Complete Fact Sheet Fields
DISEASE OVERVIEW
Name of disease:
Hantavirus Disease (HCPS / HFRS)
Causative agent:
Orthohantavirus spp., family Hantaviridae. Key strains: Sin Nombre virus (USA), Andes virus (South America), Hantaan virus (Asia), Puumala virus (Europe)
Short description:
Hantavirus is a zoonotic viral disease transmitted from infected rodents to humans. In the Americas it causes Hantavirus Cardiopulmonary Syndrome (HCPS); in Europe and Asia it causes Haemorrhagic Fever with Renal Syndrome (HFRS). Andes virus is the only strain with documented human-to-human transmission.
EPIDEMIOLOGY DATA
Incidence:
10,000 to 100,000 infections per year globally (WHO estimate). Europe: 0.4 per 100,000 (2023). Americas: 229 cases reported in 2025 across 8 countries. USA: ~20 cases/year (890 total since 1993).
Prevalence:
Relatively uncommon globally. Largest burden in Asia and Europe (mainly China, South Korea, Scandinavia). HCPS cases in Americas number in the hundreds per year; HFRS accounts for tens of thousands annually in Asia.
Mortality rate:
Americas (HCPS): 20-50% case fatality. Europe/Asia (HFRS): <1-15% case fatality. USA historical CFR: 35% (CDC). Americas 2025: CFR 25.7% (PAHO/WHO).
Case fatality rate (CFR):
Up to 50% (HCPS, Americas) - 1-15% (HFRS, Europe/Asia). USA: 35%. Americas 2025: 25.7%.
Trend:
Decreasing in East Asia (China, South Korea) due to vaccination and rodent control. Stable to slowly increasing in the Americas. Europe shows year-to-year fluctuation tied to rodent population cycles. Currently increasing attention due to 2026 Andes virus cruise ship outbreak (MV Hondius, May 2026).
DESCRIPTIVE EPIDEMIOLOGY
Who is affected most?
Adults aged 20-50; median age 38-39 years (CDC). Males more affected: 62% male, 38% female (CDC). Outdoor/rural workers, farmers, hikers, military personnel. American Indian/Alaska Native populations disproportionately affected in the USA (19% of cases vs. ~2% of population).
Where is it most common?
Asia (China, South Korea) - highest volume of HFRS cases. Americas (Argentina, Brazil, Chile, Paraguay, USA) - highest CFR from HCPS. Europe (Scandinavia, Finland, Germany) - Puumala virus. USA: 94% of cases west of the Mississippi River; highest in Arizona, New Mexico, Colorado.
When does it peak?
Seasonal - peaks in spring and summer when outdoor activity increases and rodent populations are high. In Europe, peaks correlate with mast years (years of high acorn/beechnut production → rodent population booms). No strong childhood peak; working-age adults are most affected.
RISK FACTORS
Lifestyle:
Rural living, farming, forestry work, hiking/camping, military field training, cleaning barns/cabins/attics/sheds, using summer houses that have been closed over winter
Environmental:
Geographic location in endemic region, proximity to rodent habitat or forest, enclosed/poorly ventilated spaces where rodents have been present, climatic conditions that drive rodent population booms (El Niño, mast years)
Biological:
Species of rodent reservoir involved (deer mouse for Sin Nombre; long-tailed pygmy rice rat for Andes; bank vole for Puumala); viral strain determines clinical syndrome (HCPS vs. HFRS); immune status of the host
Behavioral:
Dry sweeping or vacuuming rodent droppings (aerosolizes virus), sleeping in rodent-infested dwellings, contact with rodents or their excreta without PPE, smoking (shown to increase PUUV infection risk in Europe), not sealing entry points in buildings
TRANSMISSION & PUBLIC HEALTH IMPACT
How it spreads:
Inhalation of aerosolized infected rodent urine, feces, or saliva - the primary route. Also via direct rodent bite (less common) or contact with rodent excreta touching mucous membranes. Andes virus only: limited human-to-human transmission via close, prolonged contact (household members, intimate partners) during early illness phase.
Long-term complications:
HCPS survivors may have prolonged fatigue, reduced exercise tolerance, and respiratory impairment. HFRS can cause chronic kidney disease and long-term renal dysfunction. Both syndromes can result in prolonged ICU stays and significant neurological sequelae in severe cases.
Effect on community:
Economic burden from loss of productive working-age adults (median age 38), healthcare costs from ICU-intensive management, significant psychological impact on families and close contacts during Andes virus clusters, disruption to rural farming and outdoor industry workforces.
CONTROL & MANAGEMENT / PREVENTION
Treatments or vaccines:
No licensed antiviral treatment or vaccine approved globally (WHO 2026). Management is supportive: ICU care, mechanical ventilation for HCPS, dialysis for severe HFRS. Ribavirin has been used for HFRS with limited evidence. Early referral to ICU-capable facility improves survival. Three candidate vaccines are in Phase I trials (ECDC). Inactivated vaccines exist in China and South Korea for HFRS only.
Public health programs:
Rodent population surveillance and control, integrated pest management in endemic areas, national notifiable disease surveillance (HPS reportable in USA since 1995 via CDC NNDSS), PAHO/WHO epidemiological alerts and outbreak response (most recently May 2026 for Andes virus cruise ship cluster), WHO One Health framework linking human-animal-environment surveillance.
Prevention measures:
Seal all gaps and holes in buildings to prevent rodent entry; store food in rodent-proof containers; use wet mopping (not dry sweeping) when cleaning areas with rodent droppings; wear N95 respirator and gloves when entering potentially contaminated enclosed spaces; set traps and use rodenticides in high-risk areas; avoid disturbing rodent burrows outdoors.
Recommendations for students:
If you work in rural, outdoor, or lab settings - wear an N95 mask and gloves when cleaning enclosed spaces. If you develop fever, muscle aches, and shortness of breath after potential rodent exposure, seek emergency care immediately. There is no post-exposure prophylaxis - early ICU-level supportive care is the only intervention.
QUICK FACTS / DID YOU KNOW
Did you know?
Hantavirus was first identified in the USA in 1993 during a mysterious respiratory illness outbreak in the Four Corners region. As of May 2026, an Andes virus cluster aboard the cruise ship MV Hondius made international headlines - Andes virus is the only hantavirus known to spread person-to-person.

Perfect - I now have exact numbers from WHO, CDC, and PAHO. Here are the four epidemiology fields with precise figures and their sources:
EPIDEMIOLOGY DATA - Exact Numbers Only
Incidence (per 100,000 / per year)
Global: ~150,000-200,000 cases/year total (HFRS + HCPS combined) Europe: 0.4 per 100,000 (1,885 cases in 2023 - lowest recorded 2019-2023) (WHO DON, 2026) Americas: ~300 HCPS cases/year; 229 cases in 2025 across 8 countries (PAHO/WHO, Dec 2025) USA: 0.009 per 100,000/year; 890 total cases since 1993; mean ~26 cases/year (2008-2020) (CDC) China: ~12,800 HFRS cases/year (mean, 2004-2016) (Vial et al. 2023)
Prevalence (% / per 100,000)
Global seroprevalence: 2.93% (95% CI: 2.34-3.67%) - meaning prior exposure, not active disease By region: Americas 2.43% | Europe 2.98% | Asia 6.84% | Africa 2.21% (Tortosa et al. 2024, systematic review of 110 studies) Note: active disease prevalence at any moment is very low due to acute fatal nature
Mortality rate (per 100,000)
Global: not directly calculable due to underreporting; estimated tens of thousands of deaths/year China HFRS: CFR 1.3% of ~12,800 cases/year = ~166 deaths/year USA: 35% of 890 historical cases = 311 deaths total since 1993; ~9 deaths/year Americas 2025: 59 deaths out of 229 cases (PAHO/WHO, Dec 2025) USA 2024: 8 deaths out of 20 confirmed cases (PAHO/WHO, Dec 2025)
Case Fatality Rate (CFR)
USA (Sin Nombre virus): 35.4% (CDC, historical 1993-2023) USA 2024 specifically: 40% (8 deaths / 20 cases) (PAHO/WHO, Dec 2025) Americas overall 2025: 25.7% (59 deaths / 229 cases) (PAHO/WHO, Dec 2025) HCPS general range (Americas): 20-50% (WHO Fact Sheet, 2026) HFRS (Europe/Asia): <1-15% depending on strain (WHO Fact Sheet, 2026)
- Puumala virus (Europe): ~1%
- Hantaan virus (Asia): 5-15%
- Seoul virus: 1-2%
Trend
Decreasing in East Asia - China and South Korea incidence has declined significantly over recent decades due to inactivated vaccines and rodent control (WHO, 2026) Stable to increasing in the Americas - Argentina 2025 CFR jumped to ~30%, up from 15% historical average (AP News, May 2026) Fluctuating in Europe - tied to rodent population cycles; 2023 was the lowest rate in 5 years at 0.4/100,000 Overall global trend: stable, but the May 2026 Andes virus cruise ship cluster (MV Hondius, 10 cases, 3 deaths) has raised international surveillance
